If the "HP Integrated Module" still shows up w/ the yellow exclamation mark, double click on it and select the Driver tab then click the Reinstall Driver button. Hopefully, it can automatically locate the correct drivers for you. If not, go through the tabs and see what information is provided and post that information here. Hope that helps.

Obviously, the files that worked for me may not work for you. Different laptop etc but you may find something similar if you have a poke around inside the Software - System management section in your own laptops driver files section.

Re: NC6400 Card Reader Not Working - Showing in Device Mgr

Still not working. I've installed every piece of driver / software off the driver page for my laptop and still nothing.. Like I said, it shows up in device manager, but doesn't do ANYTHING when I insert the card..

I had this happen to me with another HP laptop before as well.. After formatting and reinstalling XP from scratch on it and downloading the drivers from their site it wouldn't work.. I ended up finding the CD that came with the laptop and installed those drivers for it and poof.. It worked..

Sadly, I don't have the CD that came with this one :(

The "HP Integrated Module" is the bluetooth module and I don't use it so I don't want to install the bloatware that is bluetooth..

Re: NC6400 Card Reader Not Working - Showing in Device Mgr

These guys will maybe have the restore and driver CDs for your make/model of laptop.Only snag is that they are in UK and they aren't cheap.I can say from personal experience that they are very efficient though. I ordered my disks at 3:30 pm and received them at 8am the next morning.Won't hurt to send them an e-mail, huh?
